Make sure that you are using the latest download from the web site. 
There was a bug here with casting for C++ that is fixed in the code 
generation templates for the current tool download. 3.1.2-1 is the jar 
you will get from the web site download page.

Also look out for a patch to the C runtime later this week to fix an 
issue with converting some tokens to strings.
